Enabling exclusive mode (device-level) Note: "Exclusive" typically means the driver opens the device for single-process access. Implementation depends on driver support; the vendor may expose an API, registry key, or tool to enable exclusive access. Common approaches:
Vendor utility: Run the Jinka configuration utility (if provided) and enable "Exclusive Access" or similar option. Registry flag: Some drivers use a registry DWORD, e.g., HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Jinka721\Parameters\ExclusiveMode = 1. Only set if vendor documentation specifies exact key/name. Open-by-name: Applications obtain exclusive access by opening the device handle with exclusive flags (FILE_SHARE_NONE). Ensure the application is designed to request exclusive access. Service/driver settings: If driver supports IOCTL to toggle exclusivity, use vendor-supplied CLI or SDK.
